SASH-OPERATING MECHANISM.

Application filed. February 26, 1825. Serial No. 11,662.

This invention relates. to sash operating mechanisms and the obgectof the invent on is to provide a sash .operatmg mechanism in V which the sash may be'locked at any point rotation of the crank.

within its path of travel. Another object ofthe invention is toprovide a sash operating mechanism in which the'mechanisni is unlocked at the beginning of rotation of the operating crank and is locked again upon cessation of rotation thereof." A further, object of the invention is to providea sash operating mechanism in which the sash is s ring supported at two points throughout t e path of travel in order to counterbalance thesash and allow it to be raised as easily as loweredj A further object of the invention isto providea sash operating mechanism compr sing a pivoted lever adapted to be raised or lowered by rotation of the crank to raise orlow'er the sash. Another object of the'invention is to provide a sash operating mechanism in which the sash may be completely lowered and raised by one complete These objects and the several novel features of the invention are hereinafter more fully described and claimed and thepreferred form of construction by which these objects are attained is shown in the accompanying drawings in .30 A

As shown in Fig. 1a frame 1 is provided having a window'glass 2 slidable vertically therein and providedwith a sash 3 having a way 4 therein. 'A cross member 5 is pro vided for the frameand a metal plate 6'is secured to the member 5, the member 5be;

ing cutaway behind the platefi as'shown'in dotted lines 7 in Fig.1. 1 A lever 8 shown in Figs l'and is pivotally mounted on the inner side-oftheplate 6at 9 andis provided with a slot 10 in the end thereof in which a pm 11 is adapted to ride. This pin 11, as shown in Fig. 2 is mounted in a block 12 which is slidably mounted on the-vertical guide rod 13. The guide rod 13 is secured by means of a nut 14 shown in Figs. land 5 to the plate 6 at theupper end and at the lower end is secured in a block 15 mounted on the lower frame member or sill'16. To limit movement of the block 12 on the guide rod 13 aslot 17 is provided in'the plate 6 'and'the extreme end of the pin 11 extends through this slot as shown in Figs. 1, 2 and 5. Pivotally mounted on the pin 11 on'opthe rod 13 and a pair of crossed arms 26 and 27 are'pivotally mounted at their intersection on the block 25. At the lower end the arm 26'is' pivotally connected to the arm 23 at 28 and the other arm 27 is pivotally connected to the arm 21 at 29. If desired a flat coiled spring indicated by dotted lines 30 may be provided atfthis'point which tends to extend the. arms though the device will operate eflici'ently without the use of. the spring- At the upper end the arms 26 and 27 are outturned and are each provided with a roller 31 riding in the way 4 in the sash 3 as shown in Figs. 1 and ,5. By jthisconstruction by raising. orlowering the rods 18 and 19 the crossedarms maybe extended or contracted to raise or lower the sash. The plate 6 is provided with araised portion 32 in the center shown in Figs.1 and 2 and the portion of the plate about this raised portion is provided with a series of apertures 33 arranged circumferentially A member 34 is rotatably mounted in this raised portion and is provided with squared end 35 to which a crank maybe secured- This member 34: is provided with a squared portion 36 on which a circular plate 37 is mounted, the

turein the raisedportion 32 and allows ro-.

tation of the member 34 in the plate 6. A The member S ll, is also provided with a cylindrical portion 88 having a flange 39 at the end. and a coiled spring a0 is positioned on the portion 38 and tends to hold the plate 4-11 in engagement with the plate 37.. The plate 41 is provided with a series of ball recesses 12 in each of which a ball 43 is mounted. l iiicse recesses as shown in Fig. t are longer than the ball and the bottom of the recesses are inclined toward the center as shown. The plate 37 is provided with a recess l-l fitting each ball as shown in, Fig. at so that the balls are carried by the plate 37. The plate it as shown in dotted lines in Fig. 1 is provided with an extending pin to which extends through a slot -16 providedin the plate 3'? so. that the plate 37 may be turned in relation to the plate all to a slight extent, the plate l1 being rotatably mounted in relation to the crank while the plate 37 is secured thereto. The plate ll is provided with a pair of upwardly extending diametrically opposite lugs l-Y which normallv engage in the apertures as shown in Figs. 1 and 2 thus preventing, movement of the sash operating mechanism. The plate L1 is also provided with a pin 48 which, engages in the cam slot -19 in the lever S and controls movement thereof.

To operate the. device the crank is turned which turns the member 54: and plate 37 secured to the portion 36 thcreot. The plate 37 carries the balls LB which travel up the inclined sides of the recesses 42 thus press ing the plate 41 outwardly against the tension of the spring 4L0 and withdraws the lugs 4.7 from the apertures 33. In this period. o'l', travel the pin 45 travels around to the end. of the slot 46 and" the pin engages the end of the slot and turns the plate 4H with the plate 37. As the plate 4.1 is turned the pin 48 which is secured. to the plate =11 and extends through the slot 19 in the arm 8. is turned thus moving the arm 8 down ward on its pivot 9 and moving the member '12 downwardly on the guide rod 13. The rods 18 and 19 which are connected at the upper endto the block 12 force the arms 2t and 23 outwardly on their pivots until the sash reacl'ies the lowermost position shown in Fin. 6.. This movement of the sash from the raised position to the lowered position, is accomplished by a. one-halt rotation of the crank and by returning the crank from the position shown in; Fig. 6 to that shown in Fig. 1 the sash is again raised. Upon release of the crank at any position the tension of: the spring 40 forces the plate 4:1 to move about so that the balls let are positioned in the bottom or deepest part of the recesses L2 which causes the lugs 4:7 to move into the respective apertures 33 and thus lock the device in position the pin brine then positioned in the center of the slot 16. By this arrangement the sash may be raised or lowered by a half turn of the crank and by providing the springs 30 the raising of the sash may be accomplished with as much ease as the lowering of the sash. providing a. sash operating mechanism composed p actically entirely of sheet metal parts and rods a construction of low manufactoring cost is provided which has at the same time all the advantages of higher priced mechanism oi this type with the further advantages oi locking at any point.

From the foregoing description. it becomes. evident that the device is very simple and eflicient in operation, will not readily get out of order, is composed of few parts and is of consequent low manufacturing cost. and provides a device which accomplishes the objects described.
